Right because we should crucify someone once they get overweight. They no longer are a person. So clearly just because Ashley Fink is overweight she no longer has feelings and no longer should be accepted.
That's the very reason Glee exists and why Glee is popular. Not the songs. Not the acting (which I'll agree some of their covers leave alot to be desired, but their acting has never been a problem.) To send the message it's okay to be an outsider. You're on a message board for probably the nerdiest thing there is, superheroes. You've probably at somepoint felt like an outsider. Still don't see the appeal?
